Since his birthday fell on the same day as the premiere of his buddy Chris Evans’s Captain America: The Winter Soldier, Robert threw together his own screening of the flick and invited a bunch of kids and their parents.

“What better way to spend my birthday than recognizing the cosmic miracle of Captain America 2 opening the same day?” he posted on his Facebook page. “Gonna wrangle about twenty kids to watch it with and partaaaaaaaaaaaaay Marvel-style!!!”

Robert is so awesome, he shared a live pic of the event on his Facebook page, captioning it, “Let the partaaaaay begin!!!”
